9% less electricity than the median of 31 comparable 250โ€“349 L chest freezer registrations (303 kWh a year). It uses less than 52% of them. At 33c/kWh that is about $9 a year less than the median, $92 over 10 years.

Uses 34% less than the maximum allowed for its size and type under the minimum energy performance standard (417 kWh a year MEPS level).

Cost = label kWh ร— 33c/kWh in NZD; change the price above to your tariff.

How efficient is it for its size?

kWh per year. Bar: the middle 80% of 31 comparable 250โ€“349 L chest freezer registrations. Dot: this model (below the median). Hover or tab to a mark for its value.

Cohort: every currently registered 250โ€“349 L chest freezer sold in New Zealand, counted once per registration. Star ratings already account for size through the GEMS adjusted-volume formula; this comparison is in raw kWh against models a buyer would actually consider instead.

Gross volumes exclude shelving. Fresh food = fresh food, chill and cellar compartments; frozen = freezer, two-star and ice-making (zero-star) compartments. Adjusted volume weights frozen space more heavily and is what the government uses to set the star rating for the size.
